Research Description

I am a sedimentary petrologist with research interests developed around problems identified in the field that can be explored through the study of sedimentary rocks in thin section, and with other petrographic methods. I work with sedimentary successions of all ages, with most of my research in the US based on Lower Paleozoic strata of Ordovician and Silurian age, including decades of work on Ordovician K-bentonite beds.
